AZDelivery Blue Pill Microcontroller Development Board Module with ARM Cortex M3 Processor compatible with STM32 Including E-Book!

When I've finished the current Arduino project, this would appear to be the next step-change in capability and integration. I'm looking forward to experimenting with it.

This is not the exact board made by chines, the USB port is not working at all.

Product as describedGood value and prompt delivery. Highly recommended.

Thank you!

This board had a CH32 chip, not an STM32. The CH32 is a cheap copy of the STM32 and is not 100% compatible. Specifically, it does not support the STM32 serial programming feature where you can program it using a USB to serial board. It also cannot be programmed using the USB port out of the box, although I knew that already.You will need an st-link v2 programmer to program this board and even then you will have problems, as the CH32 does not behave exactly the same as the STM32 with regards to programming. After several hours, I managed to program the board using platformio. For anyone who's made the same mistake that I did and bought one of these, the platformio.cfg file that I used is below:[env:bluepill_f103c8]platform = ststm32board = bluepill_f103c8board_build.mcu = STM32F103C6T6upload_flags = -c set CPUTAPID 0x2ba01477framework = arduinoWith these settings I was able to flash a modified blink program to the with an st-link v2 programmer and both boot jumpers set to "0".But really, I suggest avoiding these altogether and getting something with a genuine STM32 chip.Also, to get the "free e-book", you need to sign up with AZ-delivery's shopping site. No thanks, I'll pass on that.

it's hard to give these more than 1 star. It is not made clear that these boards are a Chinese variation of the STM32F103 produced by WCH, CH32F103. The CH32F103 is not a 1:1 clone of the original ST chip, while it does appear to have some interesting additional features it is not fully compatible. The description really needs to make this clear to buyers.Datasheets for the CH32F103 are at present only available in Chinese language. It does not appear to support programming via UART and only via SWD which means you need a ST-Link, you cannot use a FTDI to write to board.This wasted hours and hours of my time, and while I did eventually flash these after borrowing a friends ST-Link these boards are useless as the compatibility is unknown.

Is a cheap chineese version (CH43 instead stm32) which make program the board really difficult with a different behaviour every time that you plug the board. Money wasted. I can not ask for a refound because I already soldered the headers.

This is not a genuine STM32F103, but a Chinise knock-off CS32F103. Do not buy.
